Regular or Premium for highway driving/heavy loads
 
Anyone ever experiment or have experience with 87/93 fuels for highway driving and/or heavy loads? I may be taking a trip into the mountains with a fully loaded vehicle (3-4 people and hiking gear) in the next few weeks and I wanted to get some feedback regarding performance.

I always run premium. I get better mileage and the car just runs and performs better. If you pay .10 per gallon more and have a 12 gallon tank that's $1.20 more per tank. Well worth it.

And if you don't have it already, get the Injected Tuner!

Did you work out the numbers? You get better mileage but it costs more. Yeah I've fallen back on keeping up with the tuning threads, need to check out prices. Still have time on my warrenty still though.

Ten cents?? That was like ten years ago.
Premium is usually forty cents a gallon more now.

It is 15 cents more here. I was making it simple for math purposes. Do the math, pencil it out. I find it more valuable.

Regardless of cost, for hauling 4 adults on grades I would use 93 simply to maintain my sanity. Even just putting one adult in the car is noticeable on flat roads. Even if you normally only use 87, I would bump it up just for the trip.

Premium also keeps the transmission in check if you have a dct. The only problems I have are when I run 87.

While previous posters have mentioned why running premium can help, this specific l;oad you are doing is not going to change anything, premium doesn't have more power.

Agreed with the 1 extra adult. My passengers will be hefty passengers, so that's what got me thinking about this. I'll give it a shot for sure.
